Cultivar or Taxon


Citrus x aurantium L. X Citrus japonica Thunb. (sensu Mabberley 2004); Citrus unshiu Marcov. x (Fortunella japonica (Thunb.) Swingle X Fortunella margarita (Lour.) Swingle 'Meiwa') (sensu Swingle and Reece 1967; sensu Tanaka sec. Cottin 2002)



Hodgson (1967) noted that: "The name given to this class of hybrid is misleading since its parentage involves a mandarin rather than a true orange (C. sinensis or C. aurantium). So far as the writer has been able to ascertain, only one cross was made and one variety named ([Swingle and Reece 1967])."



Crown compact or dense, not weeping. First year twig surface glabrous; second or third year twig surface striate; thorns absent or not persistent; prickles absent or not persistent. Petiole glabrous, length short or medium, wings narrow, adjoining the blade. Leaflets one, margin bluntly toothed, shade leaflet blades flat or weakly conduplicate, sun leaflet blades weakly or strongly conduplicate. Leaflets sweetly orange-like when crushed. Fruit as broad as long or longer than broad, rind yellow-orange (11) or orange (12), rind texture slightly rough (4-5), firmness leathery, navel absent, flesh orange, taste acidic-sweet or sour.
